Credits are based on your total wages and self-employment income for the year. You might work all year to earn four credits, or you might earn enough for all four in much less time.
The amount of earnings it takes to earn a credit may change each year. In 2022, you earn one Social Security or Medicare credit for every $1,510 in covered earnings each year. You must earn $6,040 to get the maximum four credits for the year.
积分基于您当年的总工资和自雇收入。 您可能全年工作以获得四个学分,或者您可能在更短的时间内获得足够的四个学分。
赚取信用所需的收入金额可能每年都在变化。 在 2022 年,您每年每获得 1,510 美元的承保收入,即可获得一份社会保障或医疗保险抵免额。 您必须赚取 $6,040 才能获得当年最多四个学分。
